基于OpenMP编程模型的多线程程序性能分析

Based on OpenMP programming multicore multithreaded program performance analysis of the model

并行化程序的出现大大提高了应用程序的执行效率,多核程序设计时需要对程序的性能进行考虑。本文重点讨论OpenMP编程模型中多核多线程程序在并行化开销、负载均衡、线程同步开销方面对程序性能的影响。

The emergence of the parallel program has greatly increased the application execution efficiency, multi-coreprogram design needs to consider the performance of the program. This article focuses on OpenMP multi-core multi-hread program in the programming model in parallelization overhead, load balancing, thread synchronization overhead aspects effect the performance of the program.
